Abstract
The utility model discloses a ventilating structure for a light-transmitting cover of an LED (Light Emitting Diode) lamp. The ventilating structure comprises a light-transmitting cover, wherein the light-transmitting cover is made of a PC (Poly Carbonate) material; a plurality of stripped slots are formed in the surface of the light-transmitting cover; and the cross sections of the stripped slots are V-shaped. The light-transmitting cover is made of the PC material, the stripped slots are formed in the surface of the light-transmitting cover, and a vertical air convection channel is formed on the lower surface of the lamp, so that the heat radiating effect of the whole lamp is enhanced under the drive of air circulation; the cross sections of the stripped slots are V-shaped, so that rays generated by a light source can not be directly emitted out, and dazzle light is eliminated after multiple refractions; and the ventilating structure is formed at one step through mould injection, so that raw materials can be saved by 30-40%.
Description
Technical field
The utility model relates to the LED technical field, relates in particular to a kind of aeration structure for LED light fixture diffuser.
Background technology
Along with the development of light source LED of new generation in the lighting field application study, the very fast expansion of the market share of LED light fixture, but produce large calorimetric during LED work, heat is distributed life-span and the light decay of not going out again to light source and is produced significant damage, mostly the structure of traditional light fixture is hermetic type, a kind of aeration type diffuser can be arranged, the unique texture design of cooperated with LED light fixture self, produce a kind of air flow effect of integral body, make the internal temperature of system, by the effect of convection current, reduce rapidly, thus life-span and the optical attenuation of raising LED.This patent is exactly an a kind of invention based on this imagination, and is simple and practical, also has the saving material, and anti-function of dazzling light is a kind of structural design of energy-conserving and environment-protective.
The utility model content
The utility model purpose is exactly in order to make up the defective of prior art, a kind of aeration structure that is used for LED light fixture diffuser of good heat dissipation effect to be provided.
The utility model is achieved through the following technical solutions:
A kind of aeration structure for LED light fixture diffuser includes diffuser, and described diffuser adopts the PC material, has a plurality of bar-shaped troughs on described diffuser surface, and the cross section of described bar-shaped trough is V-shape.
Described diffuser is to annotate one-shot forming by mould.
The utility model has the advantages that: the utility model adopts the PC material, open bar-shaped trough on its surface, make light fixture form the passage of air up and down convection current at lower surface, make light fixture integral body under the drive of air circulation, radiating effect promotes, the bar-shaped trough cross section is V-shape, the light that light source produces can directly not penetrate, and after repeatedly reflecting, has eliminated and has dazzled light, annotate one-shot forming by mould, can save raw material 30%-40%.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is A-A profile in Fig. 1.
The specific embodiment
As shown in Figure 1, a kind of aeration structure for LED light fixture diffuser includes diffuser 1, and described diffuser 1 adopts the PC material, has a plurality of bar-shaped troughs 2 on described diffuser 1 surface, and the cross section of described bar-shaped trough 2 is V-shape.
Described diffuser 1 is to annotate one-shot forming by mould.
Claims (2)
1. aeration structure that is used for LED light fixture diffuser, it is characterized in that: include diffuser, described diffuser adopts the PC material, has a plurality of bar-shaped troughs on described diffuser surface, and the cross section of described bar-shaped trough is V-shape.
2. a kind of aeration structure for LED light fixture diffuser according to claim 1, it is characterized in that: described diffuser is to annotate one-shot forming by mould.
