The utility model relates to an LED floodlight, in particular to an LED light gathering lamp with bowl-shaped cooling fins and graphite for heat conduction. The LED light gathering lamp is characterized in that a light-emitting radiating assembly is composed of an LED light emitting crystal module (1), a graphite flake (2), a heat conduction module covering board (3), a front outer shell (6), the bowl-shaped cooling fins (4) and a rear outer shell (5), a reflection cover (8) and a light transmittance slice (7) cover the front outer shell, an LED driving source (10) is placed inside a power driving box (9), an E-type threaded lamp cap (11) covers the power driving box (9), and all the parts are fixed together through a mechanical method. Due to the fact that the bowl-shaped cooling fins of the LED floodlight and a lamp body are combined into a whole, the size is reduced, weight is lightened, the radiating area is enlarged, radiating conditions are improved, and the service life is prolonged. Due to the adoption of the E-type threaded lamp cap, traditional lamps can be conveniently updated and exchanged.

Description

A kind of LED light harvesting lamp of graphite heat conducting bowl-type fin

Technical field

The present invention relates to a kind of LED illuminating lamp, specifically a kind of LED light modulation collection of graphite heat conducting bowl-type fin.

Background technology

As the LED illuminating lamp of environmental protection and energy saving, the sixth of the twelve Earthly Branches, the light source of LED did not have infrared and ultraviolet by people's cognition in recent years, and long service life luminous efficiency height, and this is that conventional incandescent is incomparable.Install for convenience, improve LED brightness, many factories are again with led moduleization, carry out the integrated encapsulation of COB, promoted the extensive use of LED in lamp lighting, because LED is the solid luminescence body, its operating temperature directly influences its characteristics of luminescence, a Mechanical Builds of suitable row is mutually arranged in the cooling system of LED light fixture for this reason, and the quality of this system has determined weight and the cost performance of light fixture again.Because heat sink material and form in the LED Design of Luminaires are varied, also there are very big poor Iso in cost and efficient.Thereby design the LED light fixture that a cost is low, in light weight, efficient is high, easy to use, will go into illumination market Wei Jin and create necessary condition.

Summary of the invention

The utility model is fitted the technical requirement of portable lighter tool, and a kind of LED light harvesting lamp of graphite heat conducting bowl-type fin is provided, and it is a kind of illumination height, and is in light weight, the outward appearance smoothness, and easy to use, technology is reasonable, good heat dissipation effect, the light of being convenient to produce.The utility model is by there being the integrated encapsulated LED luminescent crystal of COB module (1) to be placed on the graphite flake (2) of heat radiation, combine with heat conduction module cover plate (3), front casing (6), bowl-type fin (4), rear casing (5), installing hole by the bowl-type bottom surface connects power drives box (9), settle LED driving power (10) in the box, cover plastics " E " type screwed sockets (11), the reflection shield (8) of setting-in light harvesting function before the LED light emitting end surface covers light transmission piece (7) at the bead of front casing.

1. described heat radiation graphite flake is that a slice thickness is the bottom surface that 1 millimeter smooth thin slice ， And is covered with rear casing.

2. described bowl-type fin is one and passes through the bowl-type fin that cold-working is processed with the fine aluminium making, and Fabric has the thermal hole of definite shape and quantity on the sidewall of bowl-type.

3. described front casing and rear casing are formed the shell of the luminous heat radiation of light harvesting lamp.Leave the air inlet seam of 4 millimeters heat transmission before and after after the assembling between shell, have the gas port of certain area at the bowl root periphery of rear casing.

4. the reflection shield of setting-in before the described LED light emitting end surface, the pyramidal surface reflection shield of being formed by eight trapezoidal faces with reflection function.

5. the light transmission piece on the described front casing bead is suppressed by transparent plastic.

The above-mentioned technical scheme following advantage of comparing with existing LED light fixture:

1. because the LED light harvesting lamp of graphite heat conducting bowl-type fin, the structure of folding before and after the lamp body shell becomes, balanced area of dissipation has improved radiating condition.

2. owing to the LED light harvesting lamp of graphite heat conducting bowl-type fin, whole light fixture has used the built-in slim bowl-type fin of preparing, and has increased radiating surface, compares with existing aluminum " heronsbill " heat radiation light fixture, can save 1/3rd metal material.

3. owing to the LED light harvesting lamp of graphite heat conducting bowl-type fin, the LED crystal module of use is placed directly on the graphite radiating sheet, effectively reduces the operating temperature of LED luminescent crystal module.

4. because the LED light harvesting lamp of graphite heat conducting bowl-type fin is installed " E " type hickey of having selected standard for use, made things convenient for the more Change to incandescent lamp and electricity-saving lamp.

5. owing to the LED light harvesting lamp of graphite heat conducting bowl-type fin, adopt the structural manufacturing process of punching parts in the manufacturing, production cost is lower, is convenient to extended use.
