Description

LED daylight lamp

Technical field

The utility model relates to a kind of fluorescent lamp, specifically a kind of LED daylight lamp.

Background technology

LED is as a kind of luminescent device directly converting electrical energy into visible ray and radiant energy, be widely regarded as 21st century top quality green light source, it has a series of advantage, as low in operating voltage, power consumption is little, the life-span is long, and LED itself is all pollution-free with manufacturing process, stable and reliable for performance, under the policy guide of energy-saving and emission-reduction, be widely used in lighting field.

For LED fluorescent tube light source characteristic, heat dissipation design and manufacturing technique requirent particularly important to radiating effect during light source works, the heat more produced to the light source of LED fluorescent tube own is also comparatively large, if heat dissipation design and production technology are then can greatly reduce the service life of light source and the decay of function to the parameter not being designed into its application in this respect; LED fluorescent tube is selecting the heat sink body that on heat sink material, general use aluminium alloy is light fixture for this reason, improves radiating effect with this.Add and consider from production technology aspect, all fully dispelling the heat for making light source and radiation aluminium alloy contact completely to reach each light source point, light source must be close on radiation aluminium alloy.As CN1O3062729A discloses a kind of LED daylight lamp, it mainly comprises light source substrate and cooling base, two edges of light source substrate are embedded in two horizontal draw-in grooves of cooling base, the heat-transfer area of light source substrate bottom and the heat-absorbent surface close contact on cooling base top, in order to ensure light source substrate edge upper surface also with the inner surface close contact on edge on the draw-in groove of cooling base, need the single lead screw ex truding briquetting machine by special technological design for this reason, the outer surface on edge on extruding cooling base draw-in groove, light source substrate two edges are made to be embedded in two horizontal draw-in grooves of cooling base, between the two by the extruding of local, be riveted together, this structure light source substrate installs inconvenience, affects overall efficiency of assembling.

Utility model content

The purpose of this utility model is to provide a kind of LED daylight lamp, and light source substrate is smooth in cooling base upper surface, makes light source substrate be close to cooling base upper surface light source substrate clamping, have easy to assembly, the feature that efficiency is high by lampshade.

For achieving the above object by the following technical solutions:

A kind of LED daylight lamp, comprise light source substrate and cooling base, it is characterized in that: be planar structure at described cooling base 2 top and bottom, the both sides at top are provided with convex stupefied 21, lampshade 3 is also provided with on described cooling base 2 top, the top in lampshade 3 cross section is circular arc, the bottom opening of lampshade 3, along being provided with a card muscle 31 under the inwall of the opening left and right sides, a press strip 32 parallel with card muscle is also provided with above card muscle 31, the spacing of two press strips 32 in left and right is less than the width of light source substrate 1, fixed groove 33 is formed between card muscle 31 and press strip 32, fixed groove 33 opening portion is slightly narrow and inside is slightly wide, the width of described fixed groove 33 opening portion is slightly smaller than convex stupefied 21 and light source substrate 1 thickness sum, described convex stupefied 21 and light source substrate 1 both sides be placed in fixed groove 33.

Described lampshade is made up of acrylic material.

Described light source substrate and the two ends of cooling base are also provided with connector, and connector, by the closed at both ends of light source substrate and cooling base, two connectors at two ends is respectively arranged with spill gang socket and convex gang socket.

Only need light source substrate to be positioned in the plane at cooling base top during the utility model assembling, then by light source substrate both sides and both sides, cooling base top are convex is stupefiedly placed in the fixed groove of lampshade, opening portion width due to described fixed groove is slightly smaller than convex stupefied with light source substrate thickness sum, card influential point of tendons props up convex stupefied bottom, and press strip side pressure is at light source substrate upper surface, thus light source substrate is tightly fixed on cooling base, the while that light source substrate being fixed on cooling base by the utility model lampshade, self has also fixed on cooling base, the installation of lampshade and light source substrate once completes, simultaneously because light source substrate is flattened on cooling base top, both sides do not have shield, lighting effect is better.

Detailed description of the invention

As Figure 1-3, a kind of LED daylight lamp, comprise light source substrate 1 and cooling base 2, be planar structure at described cooling base 2 top and bottom, the both sides at top are provided with convex stupefied 21, the lampshade 3 that acrylic material is made also is provided with on described cooling base 2 top, the top in lampshade 3 cross section is circular arc, the bottom opening of lampshade 3, along being provided with a card muscle 31 under the inwall of the opening left and right sides, a press strip 32 parallel with card muscle is also provided with above card muscle 31, the spacing of two press strips 32 in left and right is less than the width of light source substrate 1, fixed groove 33 is formed between card muscle 31 and press strip 32, fixed groove 33 opening portion is slightly narrow and inside is slightly wide, the width of described fixed groove 33 opening portion is slightly smaller than convex stupefied 21 and light source substrate 1 thickness sum, described convex stupefied 21 and light source substrate 1 both sides be placed in fixed groove 33.

During the utility model assembling only need light source substrate 1 to be positioned in the plane at cooling base 2 top, then light source substrate 1 both sides and both sides, cooling base 2 top convex stupefied 21 are placed in the fixed groove 33 of lampshade 3, width due to described fixed groove opening portion is slightly smaller than convex stupefied 21 and light source substrate 1 thickness sum, when convex stupefied 21 and light source substrate 1 both sides be placed in fixed groove 33 time, card muscle 31 can prop up the convex bottom of stupefied 21, and press strip 32 side pressure is at light source substrate 1 upper surface, thus light source substrate 1 is tightly fixed on cooling base 2, the while that light source substrate being fixed on cooling base by the utility model lampshade, self has also fixed on cooling base, the installation of lampshade and light source substrate once completes, simultaneously because light source substrate is flattened on cooling base top, both sides do not have shield, lighting effect is better.

The utility model is also provided with connector at the two ends of described light source substrate and cooling base in addition, and connector, by the closed at both ends of light source substrate and cooling base, two connectors at two ends is respectively arranged with spill gang socket and convex gang socket; Coordinated by convex gang socket and spill gang socket and can realize many LED daylight lamp head and the tail and is connected, a LED can being connected into, without the need to adding connector in addition during connection, connecting convenient.
